To all whom it may concern:

Be it known that I, Jnssn A. B. SMITH, a citizen of the United States, residing in Stamford, in the county of Fairfield and State of Connecticut, have invented certain new an useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to ty ewritin machines, and is herein disclose as applled to an Underwood machine, and as particularly adapted to facilitate the rapid aligning and gaging of superposed work-sheets, such as are often used in the operation of billing.

In billing operations, it is often desired to accurately align one work-sheet or record sheet, and then align outside of it a second shfet, the two sheets being separately gaged longitudinally to,.permit the various entries made at intervals upon the record sheet to be accurately aligned one under another.

According to the present invention, a wide record sheet may be gaged by passing it down overthe' usual rear paper-table, and bringingit up in front of the platen, so that its upper end lies upon a front papertable. When g ed there, the sheet may be held in position y actuating a fingerwoe to cause feed-rolls to grasp 1t. These eedrolls are advantageously positioned at the front paper-table, and advantageously lie outside of the margins of the narrower worksheet upon which most of the original entries are to be made. The narrower sheet is then passed down within a. chute, which may be formed in the rear paper-table to carry the narrower sheet clear of the first inserted sheet, and guided upwardly between side gages which stand clear of the front paper-table, but which are, nevertheless, near enough thereto to enable the, narrower work-sheet to be gaged by them. The

usual feed-roll release andle may then be actuated to clamp both worksheets against the platen and typing may proceed.

In order to maintain the work-sheets in proper position .onthe front paper-table, provision may be made of an upwardly-ex tending-finger to engage the work-sheets at a point intermediate their edges' If desired, the finger may be mounted for m'ovement to and from its efiective position.

It will be seen that the mechanism of the present" invention is (specially adapted for -"11,and falls upon an in position, without disturbing a tally-strip lying between the same and the platen, by

means of suitable devices such as feed-rolls adjacent the front To facilitate sheets when the paper-table. insertion of the two worklaten is near one end of its travel, as it is efore being brought back for the beginning of a new line of typing, there may be provided an auxiliary wingscale, the upper edge of which, either alone or in connection the other wing-scales, may for the writing line of a brought to adjusted position. The end win scale or auxiliary wing-scale may be sufistantially of the usual construction, and may be mounted upon a lug projecting upwardly from the usual frame of the typewriting machine.

Other features and advantages will hereinafter appear.

In the accompanying serve as a gage drawings,

V Figure 1 is a fragmentary front view of an n Figure 2 is a. detail, showing a suitable mounting for the auxiliary front feed-rolls.-

Figure 3 is a sectional side view of the parts seen in Figure 1 showing the auxiliary feed-rolls cast off in full lines, and in effective position in dotted lines, and also showing a tally strip device mounted upon the machine.

Figure 4 is a dis view of the principa ure 1.

When it is desired to align an inner wide work-sheet 10, so that it may be typed at the proper column upon the typewriting machine, it is passed downwardly over a rear paper-table 11 between adjustable side gages 12, which serve to center it upon the platen, andthen the work-sheet, after passing beneath the platen, is guided upwardly by the front extension 13 of the paper-table upper front papertable -14, comprlsing, two sections which may be adjustably carried u on a support 15, suitably mounted u on t e end plates 16 and 17 of the shift rame in which the platen 18 is journaled by its axle 19.

rammatic perspective with the upper edges of work-sheet being parts shown in Figthrough openings 25 thereof, so that the work-sheet 10 is gripped between the two sets of feed-rolls 23 and 24 mounted on shafts 26 and 27, respectively. The shaft 26, on which feed-rolls 23 are held in adjusted position by means of collars 23 and set-screws 23", may be swung rearwardly, in the manner described, because it is fast upon rock-arms 28, which, in turn, are fast upon short shafts 29 projecting inwardly from brackets 30, of which there is one mounted upon each end plate 16 and 17 The shafts,

29 are journaled in their respective brackets 30, and normally press the feed-roll or rolls 23 rearwardly because each shaft 29 carries upon an extension thereof a cam 31, against which bears a follower 32, which is drawn by a spring 33, to center the follower 32 in a depression 34 of the cam 31.

When it is desired to move the feed-rolls 23 forwardl in the manner described above, the ger-piece 22 is actuated to move the shaft 26 in the direction desired against the tension of the spring 33. The

follower 32 may be ivoted at 35 upon an extension of the bra'c et 30,-and the spring 33, which is attached to the follower 32 at one end, may be attached at its other end to a pin 33.

After the work-sheet 10 and a carbon 37 therefor have been adjusted at the desired position, a second narrower outside worksheet 38 may be adjusted in position by passing it down within a de ression or chute 39 of the aper-table 11, w iich serves to carry it for t e most part clear of the carbon associated with the work-sheet 10. The de pression 39 merges at the front of the machine into the front extension 13, with the result that the sheet 38 is carried upwardly in front of the platen to the paper=table 14. The work-sheet 38 may be gaged at its sides by the side walls 49 of the depression 39, nd these walls co-operate with arms or side gages 41 fast upon the shaft 26 to accurate y center the work-sheet 38 u on the paper table 14 and upon the un erlying work-sheet 10. The arms 41, which serve as side gages for the work-sheet 38, may always stand clear of the pa r-table 14, but, as indicated in the dottedno position of the front feed-rolls 23 in Figure 3, they 'wheel' 18.

may be brought close enough to the front pa er-table 14 to enable them to be readily uti izedas side ages.

When the wor -sheet 38 has been aligned at the desired line by the win scales 21, the usual main feed-roll casting-o lever 42 may be actuated to rock the release shaft 43-and allow the usual feed-rolls 44 and 45 to be thrown a ainst the platen 18, which may be actuated y means of finger-wheels 18* or line-spacing mechanism including a ratchet- The work-sheets 10 and 38 thereafter are fed together, and, to facilitate their. feeding, if necessary, the typist may cast off the feed-rolls 23. To facilitate the adjustment of the front paper-table 14 to suit various widths of sheets, it may be formed in two separated parts, each provided with a pair of openings 46 in the form of slots at the bottoms of depressions 4?, to permit headed screws 48 threaded into the support 15 to hold the parts in any desired positions of adjustment. It will be seen that in order to adjust, to any" reat extent, the sections or arts of the ront papertable 14, it will feed-rolls '24 alongthe shaft 27. To this end, the feed-rolls 24 may be adjustably se cured on shaft 27 by any suitable means (not shown). When the sections of paper: table 14 and the feed-rolls 24 are thus adjIIStBdythG-fBQd-IOHS 23 may be correspondmgly adjusted by loosening the set-screws 23 and 50, which respectively hold the collars 23 and the collars 51 of the arms 41' in osition;

necessary to adjust the 11 order to avoid the use of unnecessary material and to render the parts as accessible and as open to view as possible, the upper paper-table 14 may be largely cut away as at 53, thus enabling it to have long turned-up margins to serve as edge gages 20, while the body of the table is comparatively short. In order to hold the two worksheets close to the face of the table 14, there may be provided a finger 54 extending upwardly to lie almost flush with the surface of the work-sheets as they lie fiat upon the paper-table 14, said finger being secured to a block 54 pivoted at 55 uponthe front bar. 56 of the t pewriter carriage and yieldlngly held in esired position, either effective or ineffective, by means of a leaf spring is at one end of its travel, t ere may be provided auxiliary wing-scales 57 of which one,

near the left-hand limit of the travel of the t pewriter carriage, is shown in Figure-1.

1s wmg-scale may be journaled upon a lug 58 usual frame 60 of the typewriting machine,

fast to an upward extension 59 of the and may be held against swinging too far rearwardly underthe pressure of 1ts spring 61 by a short arm, not shown herein, of the usual kind provided on wing-scales.

When the-feed-ro1ls 23 have been swung controlled by mechanism of the same generalform as that disclosed in the patent to Hart, No. 1,281,160, dated October 8,1918. The shifting of the feed-rolls 44 and 45 to and from effective position may also be effected by means such as disclosed in said patent.

It will be seen that there are two means for feeding the wide work-sheet 10a primary feeding means including the platen 18-and the feed-rolls 44 and 45, and a secondary feeding means including the rolls 23 and 24.

The operation of the embodiment ofthe invention shown in the drawings may be summed up as follows: After the ledgersheet- 10 and bill-sheet 38 have been typed, the ma be withdrawn from the machine an replaced. by new sheets to be typed, while the tally-strip 63 may remain in the machine. Preparatory to inserting anew ledger-sheet and bill-sheet, the tally-strip 63 may be advanced in the usual way by means of the tally-strip mechanism, and also the tally-strip mechanism will be eflective to hold the tally-strip stationary while the new sheets are being inserted and adjusted to the typing position. When a ledger-sheet 10 has'been inserted, it may be adjusted relatively to the tally-strip 63, to bring the ledgcrsheet to the typing position, by means of the auxiliary rolls or collating rolls 23 and 24, while the tally-strip 63 is held in typing position by means of the tally-strip mechanism. If desired, the tally-strip 63 may be advanced after the ledger-sheet 10 has been adjusted, the ledger-sheet then being held in adjusted positionby means of the collating rolls 23 and 24, which also constitute sheet-holding rolls. While the ledgersheet is held in adjusted position by the collating rolls 23 and 24, one or more outer work-sheets, for example, the bill-sheet. 38, maybe inserted and adjusted relatively to the ledger-sheet 10, thereby to bring this outer sheet (or sheets) to the typing position. The platen feed-rolls 44 and 45 are then thrown on, and the collating rolls 23 being controlled by anism.

leased. The typing operation may then. pro.- ceed, the ledger-sheet 10 and bill-sheet 38 being line-fed b the platen and its usual feed-rolls 44 an 45, and the tally-strip 63 the tally-strip mech- Variations may be resorted to within the scope ofthe invention, and portions of the improvements may be used without others.
